Abstract

A magnetic medical treatment device and method wherein a coil received in a housing is energized with a periodic current of a predetermined frequency furnished from a power supply accommodated in the housing or disposed separately outside thereof to produce a corresponding, time-varying periodic magnetic field through the coil. A stylus formed of magnetically permeable material and electromagnetically associated with the coil means is positioned in engagement with a preselected surface zone of the body surface of an individual (patient) to selectively apply the magnetic flux to the surface zone.

Claims

1. A magnetic treatment device comprising:

coil means;

power supply means for energizing said coil means with a periodic current of a predetermined frequency to produce through said coil means a corresponding time-varying, periodic magnetic field of said predetermined frequency;

positioning means operable to position said magnetic field selectively at a preselected surface zone of the body surface of an individual;

field concentrator means constituted by a stylus member electromagnetically associated with said coil means and positionable with said positioning means for engagement with said preselected surface zone of the body surface of the individual for selectively applying said magnetic field to said preselected surface zone;

housing means for accommodating said coil means therein and carrying said stylus member to hold it at least in part projected therefrom for engagement with said preselected surface zone; and

spring means associated with said housing means for supporting said stylus member resiliently therewith to reduce a contact shock of said stylus member against said body surface of the individual.

2. The device defined in claim 1, further comprising a handle mechanically coupled with said housing means and constituting at least in part said positioning means for positioning said stylus member in a predetermined engagement relationship with said preselected surface zone of the body surface of the individual.
